Application filed October 9, 1914. Serial No. 865,831.

T 0 all whom it may concern:

Be it known that 1, CHARLES lV. S'ranxnn, a subject of the Emperor of Germany, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Axlecollars, of which the following is a specification. 7

My invention relates to axle-inclosing devices for spacing purposes, and it has special reference to split axle collars for suitably positioning electric motors on the wheel axles of electric railway vehicles and the like. I

The object of my invention is to simplify and reduce the cost of construction and to decrease the weight and number of component parts of devices of the above-indicated character.

More specifically stated, the object of my invention is to provide a split axle collar that embodies a means having the double function of securing the collar parts and an adjustable collar-positioning member together.

In the prior art, the halves of split axle collars have customarily been fastened together, in a suitable manner by -a.plurality ofbolts, and,'in order to-.permit oflongit-udinal "adjustment of'thecollar as a. whole along the shaft'or axle, some additional means, such. as separate longitudinallydi'spos'ed bolts operating in threaded lugs, have beenprovided. i

According to'. my present invention, 1 provide a multi-partor. split axle. collar, preferably of light pressed-steel construction, having longitudinallyextending abutting. lips on, the sides Zofthe split, one of the=oiiterlip surfacesbeing toothed, a correspondingly toothed collar positiomng rod adjustably I'm'eshing Ywith the toothed, lip surface and providecl.with 'boltrreceiving slots'to permit of longitudinal 'movement, and'one or'more clamping bolts extending through said slots and said lips to secure the c'ollarparts and the rod together in any desired position. Thus, the same means is provided for securing the parts'of the collar together and for positioning the collar, as a whole, along the wheel axle, and the cost, Weight and number of .parts of the collar are'all reduced.

In the accompanying drawing, Figure 1 is a view, in side elevation, of a portion of a vehicle wheel truck; Fig. 2 is a view, in end elevation, of the axle collar shown in Fig. l; and Fig. 3 is a plan view of a portion of the apparatus illustrated in the other figures.

Referring to Fig. l of the drawing, the structure here shown comprises a working member, such as vehicle wheel 1, having a suitable axle or shaft 2;. an electric motor supported by the said shaft; a predeten mined distance from the wheel I, depend ent upon the relative dimensions of the electric motor and the wheel axle, as will beunderstood, and having an axle bearing 8 that is inclosed by a portion 3 of the motor frame, of customary construction; and a niulti-part axle-inclosing spacing member or split axle collar 4.

The axle collar 4 comprises a pair of substantially identical semi-cylindrical halves 5, preferably of light pressed-steel construction, which are provided with peripheral flanges 6 at the ends nearer the electric mo tor and a pair of longitudinally-extending abutting lips 7 and S at each side of the split 9, the outer surface of the lip '7 being provided with corrugations or teeth 10; a collar-positioning member or bar 11, which is provided with a toothed surface 11 for suitably meshing with the teeth 10 of the lip 7; and a suitable-clamping means 12, such as bolts, forfastening the collar parts andthecollar-positioning bar 11 together.

The exterior surface of each flange 6 is preferably provided with a wearing-plate 13 of hard fiber or similar material which may be secured to the flange by means suitable rivets 14, the collar as a whole being positioned to cause the wearing-plate 13 to closely engage the end of the axle bearing 3 and thereby prevent, in particular, the lateral movement and consequent hammering? of the motor;

The collar positioning bar 11, in addition to having-the toothed surface 11*, is provided with a plurality of longitudinallyext-ending, centmuyaocared, bolt i' eceiving slots .15 and T16. I'Th'e clamping.meansz l2 preferably comprises a through {bolt 17, with the lower er'idof whi'cha suitable nut 18 and locl; washer l9 cooperate, and another washer 20 which is provided with longitudinally-extending flanges to prevent rotation of the bolt, is preferably disposed between the collar-positioning bar 11 and the head of the bolt. It will be understood that any suitable number of bolts may be provided, and also that the collar-positioning bar 11 may be employed on either one or both sides of the collar, as desired.

To position the collar, as a whole, at any desired place on the wheel axle, preferably in direct contact with the motor axle bearing 3, as hereinbefore described, and, in particular, to compensate for wear of'the plate 13 on the axle bearing, it is merely necessary to extend the toothed bar 11 to a point where it engages the inner surface of the wheel 1, longitudinal movement of the bar being permitted by reason of the boltreceiving slots 15 and 16; and the bolts and nuts are then tightened to secure the collar parts rigidly together and to simultaneously mantain the collar-positioning bar 11 in its desired position.

I do not wish to be restricted to the structural details or arrangements of parts herein set forth, but desire that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention:

1. The combination with a shaft or axle, a multi-part axleinclosing device and a longitudinally adjustable member, of means having the double function'of securing the parts of said device together and of securing said adjustable member to position the device, as a whole, along the said shaft or axle.

2. The combination with a shaft or axle, a working member associated therewith, a split axle-inclosing device and a longitudinally adjustable member, of means having the double function of securing the split parts together and of securing said adjust able member to position the device, as a whole, along the said shaft or axle with respect to said working member.

3. The combination with a wheel axle, a machine frame disposed thereon, a multipart axle-inclosing spacing member and a longitudinally adjustable member, of means having the double function of securing the parts of said member togetherand of securing said adjustable member to position the device,'as a whole, along the said axle with respect to said wheel and said frame.

4; In an electric railway vehicle, the combination with a wheel axle, a propelling motor partially supported thereby, a split axlecollar and a longitudinally. adjustablemember, of means having the double function of securing the collar parts together and ofsecuring said adjustable member to position the collar adjacent to said motor and at a Sonics otthis patent may be obtained, for

predetermined distance from the, corresponding vehicle wheel.

5. The combination withan axle, and a machine frame disposed thereon, of a split collar adapted to inclose said axle, clamping means for the collar parts, andmeans secured to the collar by said clamping means for positioning the collar, as a whole, along the axle. n
